A contribution to the rotation of a galaxy, due to internal structure alone, is discussed in the context of a generalized version of the theory of general relativity, whereby the space‐time metric has a quaternion structure. The radial dependences of the angular momentum of a constituent star of a galaxy, relative to the remainder of its host galaxy, are determined and compared in regard to the classical Newtonian theory, Einstein's tensor form of general relativity, and the generalized quaternion formulation of the latter theory of gravitation. The results are subject to possible observational tests.
